SaveQuest — Decentralized Group Savings with DeFi Yields

Inspiration

In Africa and other emerging markets, communities rely on informal savings systems like ajo and esusu to meet financial goals.
These systems work through trust but suffer from idle funds, manual record-keeping, and fraud risks.

We built SaveQuest to merge the trust of group savings with the automation and yield power of DeFi — bringing transparency, safety, and growth to community finance.

What We Built

SaveQuest is an onchain savings protocol on Starknet where members deposit stablecoins or wrapped BTC into shared pools.
Funds are deployed into yield-generating vaults, and the yield is rotated monthly among members, while the principal remains untouched.

[ \text{Monthly Yield Share: } Y_t = \frac{r_t \times P}{N} ]

Blockchain: Starknet (Ethereum L2)
Assets: USDT, USDC, wBTC
Model: Group savings + yield vaults = monthly rewards

How We Built It

We designed smart contracts in Cairo to handle deposits, rotations, and yield distribution.
An Express.js backend listens for contract events and automates pool updates.
The planned frontend is a React Native + native-wind app for mobile users to create and join pools seamlessly.
